Athens Water Supply and Sewerage (ATH:EYDAP) shareholders are up 10% this past week, but still in the red over the last three years

It's nice to see the Athens Water Supply and Sewerage Company S.A. (ATH:EYDAP) share price up 10% in a week. But that cannot eclipse the less-than-impressive returns over the last three years. Truth be told the share price declined 16% in three years and that return, Dear Reader, falls short of what you could have got from passive investing with an index fund.

Although the past week has been more reassuring for shareholders, they're still in the red over the last three years, so let's see if the underlying business has been responsible for the decline.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Athens Water Supply and Sewerage the TSR over the last 3 years was -7.9%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective
